Embodiment 1

[0187] If the clock is out of lock on the device and the time is out of lock at the same time, two synchronization alarm messages can be packaged for the status changes of the two synchronization alarms. The type identifier corresponding to the time out of lock; in addition, the two synchronous alarm messages carry the status information of the synchronous alarm respectively; after the ONU encapsulates the above content to form two synchronous alarm messages, it uses the OLT management channel to transmit the two synchronous alarm messages.

Embodiment 2

[0189] If the clock of the device is out of lock and the time is out of lock at the same time, two synchronous alarms of status transmission changes can be encapsulated into a synchronous alarm message, in which the type is identified as the message category code indicating that the message is an alarm, and in the synchronous alarm The message also carries the type identification of clock loss and time loss (such as the type of synchronization alarm represented by a specific identification) and status information; after the ONU encapsulates the above content to form a synchronization alarm message, it uses the OLT management channel to transmit the synchronization alarm message.

Embodiment 3

[0191] If the device’s clock is out of lock and the time is out of lock at the same time, but no ESMC message is lost, the following methods can be used to encapsulate the synchronization alarm message: carry the message type code indicating that the message is an alarm message in the synchronization alarm message; The synchronization management unit identification corresponding to the lock, time lock, and ESMC message loss is "synchronization management unit identification 427", and the corresponding synchronization management unit identification "synchronization management unit identification 427" is carried in the synchronization alarm message; Indicates the alarm number, then the first and second bit positions used to indicate clock loss of lock and time loss of lock in the alarm state table with 224 bits in the synchronous alarm message are set to 1, and ESMC The third bit of packet loss is set to 0, and the other bits without corresponding alarms are all set to 0; the mes...

Abstract

The invention discloses a method and equipment for performing synchronous alarm, which are used to solve the problem that synchronous alarm cannot be performed between ONU and OLT in the prior art. The method includes: ONU generates a synchronous alarm message after the state of the synchronous alarm changes, wherein the synchronous alarm message includes the type identification of the synchronous alarm and the state information of the synchronous alarm; the ONU sends the synchronous alarm message to the OLT, so that the OLT Synchronous alert messages identify synchronous alerts that have changed state. After the state of the synchronous alarm changes, the ONU can generate a synchronous alarm message including the type identification of the synchronous alarm and the status information of the synchronous alarm, and the ONU can transmit the synchronous alarm to the OLT through the synchronous alarm message, thus solving the problem that cannot be solved in the prior art. The problem of synchronizing alarms between ONU and OLT.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for synchronous alarming. Background technique [0002] TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access), TD-LTE (Time Division Long Term Evolution, Time Division Long Term Evolution Evolution) and other wireless standards, the relative time difference between different base stations needs to be kept within a certain range, that is, the time synchronization requirements need to be met, otherwise, when mobile terminals such as mobile phones switch between different base stations, signals will interfere with each other, resulting in a decline in call quality, Problems such as stringing and dropped calls. In a traditional method, time synchronization between different base stations is realized b...
